## Summary description

SUNGROW SG25RT is a three-phase 25 kW solar inverter designed for commercial and large residential PV systems. It features two MPPT inputs for optimized array configuration and improved energy harvest. The inverter converts DC from solar panels to grid-ready AC, supports grid connection and monitoring, and is suitable for rooftop or ground-mounted installations where reliable high-power conversion is required.

## Long description

SUNGROW SG25RT is a three-phase 25 kW solar inverter designed for commercial and large residential PV systems. It converts DC power from photovoltaic panels into grid-compatible AC and supports monitoring and grid connection functions. The model includes two independent MPPT inputs to improve energy yield and flexible string layouts. With IP65 protection, transformerless topology and smart forced-air cooling, the inverter is suitable for rooftop or ground-mounted installations that require high-power, reliable conversion.
Advantages
The SUNGROW SG25RT offers high conversion efficiency up to 98.50% and European efficiency of 98.00%, dual MPPT inputs with independent string connections, and a wide MPP voltage range (160 V – 1000 V) that supports long string configurations. It features comprehensive protection functions — including DC reverse connection protection, AC short-circuit protection, leakage current protection, AFCI, PID recovery and surge protection (DC Type II / AC Type II) — and is rated to IP65 for outdoor use. Built-in 4G communication and LED display simplify monitoring and commissioning.
Suitable for
Commercial PV systems up to 25 kW
Large residential rooftop or ground-mounted installations
Installations requiring dual MPPT for varied string orientations or shading
Sites needing IP65-rated outdoor equipment and remote monitoring (4G)

How to use
Install the SUNGROW SG25RT on a suitable wall-mounting bracket in a location that meets ambient temperature and altitude limits and provides adequate air flow for forced-air cooling. Connect PV strings to the two independent MPPT inputs using MC4 connectors (max 6 mm²), respecting the MPP voltage range and maximum input current. Connect the AC side to the three-phase grid via the OT or DT terminal (max 70 mm²) and configure grid parameters according to local grid codes. Enable built-in protections and use the LED display and 4G communication for commissioning and remote monitoring.
Usage recommendations
Verify string voltages and currents during design to ensure they fall within the MPP range and maximum input limits; apply derating above 2,000 m altitude. Use appropriate surge protection and follow local grid connection requirements. For long-term performance, keep ventilation clear and schedule periodic inspections of DC/AC connections and protective devices.
